On the Move pad - a portable multipurpose pad: User feedback.

CONTEXT/OBJECTIVE: Hard-shell toilet seats may compromise safety and hinder the participation of individuals at risk for pressure injuries (PIs) when using these facilities away from home in public, hotel, or family/friend restrooms. Moreover, people often add "wash-cloths" for additional padding for comfort, and to reduce the risk of PIs due to pressure or shearing on their wheelchairs surfaces. This study investigated the utilization of portable pads, initially designed for toilet use but adaptable to various places and contexts, while examining pad usability. DESIGN: A cross-sectional descriptive survey design. SETTING: Inpatient care, outpatient care, and community setting. PARTICIPANTS: 45 individuals at risk of PIs. RESULTS: Participants extended the use of these pads beyond toilets, employing them as wheelchair armrest and leg rest pads in other settings. Feedback from a customized questionnaire indicated high levels of usefulness (8.5/10) and ease of use (9.1/10) attributed to the pads. Among the features, the top three favored were ease of use, comfort/cushioning, and function. Participants expressed a desire for a variety of sizes and colors to enable versatile usage and suggested incorporating a pocket for storing small items. CONCLUSIONS AND RELEVANCE: Individuals at risk of PIs require cushioning not only on hard-shell toilet seats, but also for additional padding, protection and enhancing the use of wheelchairs. Rehabilitation professionals can play a crucial role in educating and training both clients and caregivers to understand PI prevention, enabling them to effectively leverage the pads in appropriate situations, thereby enhancing their comfort in their wheelchairs during social engagement.

Accessible Autonomous Transportation and Services: Design Considerations From the Perspective of Consumers and Providers.

OBJECTIVE: To understand the priorities and preferences of people with disabilities (PwDs) and older adults regarding accessible autonomous vehicles (AVs) to address existing transportation barriers. DESIGN: Two national surveys, Voice of the Consumer and Voice of the Provider, were conducted to gather feedback from accessible AV consumers and providers, respectively, in the United States. SETTING: This U.S.-based study focused on PwDs and older adults who may face transportation challenges and those who provide or design AV solutions. PARTICIPANTS: The 922 consumers and 45 providers in the surveys encompassed a diverse range of disability types, caregiver roles, and age groups (N = 967). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The main outcomes were consumer usage needs and provider preferences for features in accessible autonomous transportation. Patterns in usage needs and feature preferences through 2-step clustering algorithm were applied subsequent to the descriptive analysis of participant demographics and their responses. RESULTS: Participants strongly preferred AV features enhancing personal transportation, especially for rural medical appointments. Most sought comprehensive AV automated features. Wheelchair users emphasized accessible entrances, particularly for lower-income brackets ($25,000-$49,000). Provider priorities closely aligned with consumer preferences, reinforcing content validity. CONCLUSIONS: The study highlights the importance of prioritizing wheelchair accessibility in AVs and improving access to medical appointments, especially in rural and low-income communities. Implications include developing inclusive AV services for PwDs and underserved populations. The research establishes a foundation for a more equitable and accessible transportation landscape through AV technology integration.

Discovering Provider Awareness of Mobility Assistive Technologies and Clinical Guidelines- A Comparative Analysis with Consumer Responses.

OBJECTIVE: This study aims to enhance the accessibility and quality of mobility assistive technology (MAT) by investigating and bridging knowledge gaps between MAT providers and consumers with ambulatory limitations. DESIGN: A survey was conducted among MAT providers in the United States, consisting of sections on awareness, knowledge importance and desire, and knowledge sources. The responses were compared to data collected from consumers in a previous study. RESULTS: A total of 144 MAT providers participated, with 60% having received academic or professional training in relevant fields. Analysis revealed significant knowledge gaps between providers and consumers, particularly in AT assessment tools and knowledge sources. Moderate gaps were also observed in areas such as clinical practice guidelines, desired MAT information, and knowledge sources. However, the gaps in other areas were relatively small. CONCLUSION: This study highlights the knowledge gaps between MAT providers and consumers, hindering the optimal utilization and fulfillment of user needs. Providers possess valuable information that consumers may lack, positioning them as primary knowledge sources. Addressing these gaps through targeted interventions, improved communication channels, and enhanced education can enhance the utilization of MAT and improve outcomes for individuals with ambulatory limitations.

Evaluation of Electric and Air-Powered Shopping Scooters in Grocery Stores.

OBJECTIVE: The purpose of this study was to further previous research and gather additional information regarding the usage of motorized shopping scooters as well as feedback for improvements to an air-powered scooter. METHODS: Online surveys were used to assess individuals' shopping characteristics and experience using the motorized scooters and to gather feedback from store employees regarding their experience. K-Means clustering analysis was used to determine user demographics who chose to use the air-powered scooter versus the electric powered scooter while shopping. RESULTS: A total of 127 individuals provided informed consent, 65 individuals from Site 1 and 62 individuals from Site 2. 120 participants met the inclusion criteria and completed the survey. K-Means clustering found that age, type of personal mobility device, shopping bill total, and frequency using a motorized shopping scooter to be significant factors in whether individuals chose to use an air-powered scooter or electric-powered scooter. CONCLUSION: Motorized shopping scooters are in high demand and used by a wide variety of individuals, yet electric-powered scooters are commonly unavailable due to having dead batteries or all the devices being in use. Air-powered scooters may serve as a practical replacement for the current electric-powered scooters found in grocery and retail stores.

Accessible autonomous transportation and services: voice of the consumer - understanding end-user priorities.

PURPOSE: This study aimed to explore the requirements for accessible Autonomous Vehicles (AVs) and AV services from a consumer perspective, focusing on people with disabilities (PwDs) and older adults. METHODS: Two national surveys were conducted, capturing current transportation trends and AV priorities. Participants (n = 922) with disabilities and older adults were included in the analysis. RESULTS: Transportation choices exhibited significant divergence based on the underlying causes of disabilities, showcasing distinct inclinations and impediments within each category. AV services, encompassing family conveyance and package delivery, proved integral, but their specific desirability fluctuated in accordance with the nature of disabilities. Notably, medical appointments emerged as the foremost AV utilisation requirement, particularly pronounced among individuals with hearing impairments. Preferences for orchestrating AV rides and the preferred vehicle types displayed disparities linked to the various disability classifications. The employment of mobile applications, websites, and text messages were preferred mediums for arranging rides. Features such as automated route guidance and collision prevention garnered unanimous precedence among AV attributes. Key priorities, spanning wheelchair accessibility, user profiles, and seamless communication with AVs, were universally emphasised across all participant clusters. The study indicated a moderate comfort level with AV deployment, implying the potential for favourable reception within the population of PwDs and older adults. CONCLUSION: The study highlights the significance of considering diverse needs in accessible AV development of vehicle and infrastructure and policies.

The findings inform evidence-based interventions and programmes that prioritise accessibility needs, promoting social inclusion and equitable transportation solutions.Continued research and advocacy are essential for successful autonomous vehicle integration, catering to the needs of all individuals.

Usability and Vibration Analysis of a Low-Profile Automatic Powered Wheelchair to Motor Vehicle Docking System.

The QLX is a low-profile automatic powered wheelchair docking system (WDS) prototype developed to improve the securement and discomfort of wheelchair users when riding in vehicles. The study evaluates the whole-body vibration effects between the proposed QLX and another WDS (4-point tiedown system) following ISO 2631-1 standards and a systematic usability evaluation. Whole-body vibration analysis was evaluated in wheelchairs using both WDS to dock in a vehicle while riding on real-world surfaces. Also, participants rated the usability of each WDS while driving a wheelchair and while riding in a vehicle in driving tasks. Both WDSs showed similar vibration results within the vibration health-risk margins; but shock values below health-risk margins. Fifteen powered wheelchair users reported low task load demand to operate both WDS; but better performance to dock in vehicles with the QLX (p = 0.03). Also, the QLX showed better usability (p < 0.01), less discomfort (p's < 0.05), and greater security compared to the 4-point tiedown while riding in a vehicle (p's < 0.05). Study findings indicate that both WDS maintain low shock exposure for wheelchair users while riding vehicles, but a better performance overall to operate the QLX compared to the 4-point tiedown system; hence enhancing user's autonomy to dock in vehicles independently.

Accessible autonomous transportation and services: a focus group study.

PURPOSE: Existing automated vehicle transportation guidelines and regulations have minimal guidance to address the specific needs of people with disabilities. Accessibility should be at the forefront to increase autonomy and independence for people with disabilities. The purpose of this research is to better understand potential facilitators and barriers to using accessible autonomous transportation. METHODS: Focus groups were conducted with key stakeholders derived from people with disabilities (n = 5), travel companions/caregivers (n = 5), and transportation experts or designers (n = 11). RESULTS: The themes include describing stakeholder perceptions across all three groups by identified themes: autonomous vehicle assistive technology, autonomy vs automation, cost, infrastructure, safety & liability, design challenges, and potential impact. CONCLUSION: Specific gaps and needs were identified regarding barriers and facilitators for transportation accessibility and evidence-based guidance. These specific gaps can help to formulate design criteria for the communication between, the interior and exterior of accessible autonomous vehicles.

Accessible and affordable autonomous transportation may increase mobility and the autonomy of people with disabilities to travel spontaneously.Autonomous vehicles and services should be designed to accommodate various types of disabilities such as multimodal and multilingual device communication.Safety and liability regulatory protocols need to be developed for incidents and emergencies.Wheelchair user, especially people who use powered devices, would need systems for ingress/egress, docking, and occupant restraints.

Participatory Action Design and Engineering of Powered Personal Transfer System for Wheelchair Users: Initial Design and Assessment.

Caregivers that assist with wheelchair transfers are susceptible to back pain and occupational injuries. The study describes a prototype of the powered personal transfer system (PPTS) consisting of a novel powered hospital bed and a customized Medicare Group 2 electric powered wheelchair (EPW) working together to provide a no-lift solution for transfers. The study follows a participatory action design and engineering (PADE) process and describes the design, kinematics, and control system of the PPTS and end-users' perception to provide qualitative guidance and feedback about the PPTS. Thirty-six participants (wheelchair users (n = 18) and caregivers (n = 18)) included in the focus groups reported an overall positive impression of the system. Caregivers reported that the PPTS would reduce the risk of injuries and make transfers easier. Feedback revealed limitations and unmet needs of mobility device users, including a lack of power seat functions in the Group-2 wheelchair, a need for no-caregiver assistance/capability for independent transfers, and a need for a more ergonomic touchscreen. These limitations may be mitigated with design modifications in future prototypes. The PPTS is a promising robotic transfer system that may aid in the higher independence of powered wheelchair users and provide a safer solution for transfers.

Evaluation of Power Wheelchair Dynamic Suspensions for Tip Prevention in Non-ADA Compliant Surfaces.

OBJECTIVE: To evaluate the driving performance and usability of a mobility enhancement robot (MEBot) wheelchair with 2 innovative dynamic suspensions compared with commercial electric powered wheelchair (EPW) suspensions on non-American with Disabilities Act (ADA) compliant surfaces. The 2 dynamic suspensions used pneumatic actuators (PA) and electro-hydraulic with springs in series electrohydraulic and spring in series (EHAS). DESIGN: Within-subjects cross-sectional study. Driving performance and usability were evaluated using quantitative measures and standardized tools, respectively. SETTING: Laboratory settings that simulated common EPW outdoor driving tasks. PARTICIPANTS: 10 EPW users (5 women, 5 men) with an average age of 53.9±11.5 years and 21.2±16.3 years of EPW driving experience (N=10). INTERVENTION: Not applicable. MAIN OUTCOME MEASURE(S): Seat angle peaks (stability), number of completed trials (effectiveness), Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST), and systemic usability scale (SUS). RESULTS: MEBot with dynamic suspensions demonstrated significantly better stability (all P<.001) than EPW passive suspensions on non-ADA-compliant surfaces by reducing seat angle changes (safety). Also, MEBot with EHAS suspension significantly completed more trials over potholes compared with MEBot with PA suspension (P<.001) and EPW suspensions (P<.001). MEBot with EHAS had significantly better scores in terms of ease of adjustment (P=.016), durability (P=.031), and usability (P=.032) compared with MEBot with PA suspension on all surfaces. Physical assistance was required to navigate over potholes using MEBot with PA suspension and EPW suspensions. Also, participants reported similar responses regarding ease of use and satisfaction toward MEBot with EHAS suspension and EPW suspensions. CONCLUSIONS: MEBot with dynamic suspensions improve safety and stability when navigating non-ADA-compliant surfaces compared with commercial EPW passive suspensions. Findings indicate MEBot readiness for further evaluation in real-world environments.

Economic evaluation of wheelchairs interventions: a systematic review.

OBJECTIVE: The overall aim of this systematic review was to identify and synthesise the best available evidence on effectiveness, resource use and costs involved in wheelchair interventions of adults with mobility limitations. METHODOLOGY: This systematic review was undertaken in accordance with the Centre for Reviews and Dissemination Guidelines. The protocol for this systematic review was registered with PROSPERO International Prospective Register of Systematic reviews. The following PICOS eligibility criteria were considered: (P) Population was individuals with mobility limitations that live in their community (e.g., non-institutionalized), with aged 18 or older; (I) Intervention was mobility assistive technologies (MAT), such as manual and powered wheelchairs; (C) Comparators (Not Applied); (O) Outcome, the primary outcome of interest, was established as the cost-effectiveness of wheelchair interventions. Direct and indirect costs per unit of effect were expressed in terms of clinical outcome units, quality-adjusted life years gained, utility scores, quality of life measures and incremental cost-effectiveness ratios to inform the economic outcomes. (S) Study design was considered as a health economic evaluation (i.e., including cost-effectiveness analysis, cost-utility analysis and cost benefit analysis as well as partial economic evaluations). The Consolidated Health Economic Evaluation Reporting Standards - CHEERS, checklist was used for summarising and interpreting the results of economic evaluations. RESULTS: Sixteen studies were included, two were identified as full health economic evaluations and 14 were considered partial health economic evaluations. CONCLUSION: Only two full health economic analyses of wheelchair interventions have been conducted and both focussed on powered wheelchair provision. There are important gaps in current knowledge regarding wheelchair health economic methods and available outcome measures, which there is a great need for further research.Implication for RehabilitationSystematic reviews of health economic evaluation studies are useful for synthesising economic evidence about health interventions and provide insight in new research development.Organisations involved in the provision of wheelchairs should apply cost-effectiveness outcome measures to help raise the standard of provision, to support evidence-based practice, and to improve resource utilisation.

Current state and conceptual framework of assistive technology provision in Saudi Arabia.

PURPOSE: Assistive Technology (AT) devices provide essential means of mobility, employment, communication, social engagement for older adults and people with different disabilities, if prescribed correctly to match users' needs and goals. Regardless of the setting or location, a successful AT service delivery model includes the multidisciplinary collaboration of the people with disabilities and the specialists who have knowledge and expertise in the design and application of AT. In Saudi Arabia, unfortunately, the availability of AT devices is mainly limited to basic mobility and daily living aids such as wheelchairs and seating systems, prosthetics and orthotics, communication devices, low-vision devices, and adapted transportation equipment. The aim of this perspective is to provide clinicians and healthcare professionals in Saudi Arabia with a model for the optimisation of the provision of AT devices decision making regarding AT devices for people with disabilities by adhering to a user-centered team approach throughout the service delivery process. METHOD: The policy, human, activity, assistance, technology, and environment (PHAATE) model is used as a conceptual framework and guideline for this paper. RESULTS AND CONCLUSION: The PHAATE components could serve as a guideline for a wide range of stakeholders in Saudi Arabia (e.g., researchers, product developers, practitioners, clinicians, third-party reimbursement entities, consumers, and educators) when developing service delivery systems.IMPLICATION FOR REHABILITATIONDespite the support and funding resources of AT devices by the Saudi government, there is still the needs to increase awareness and knowledge about AT application and services, as well as optimal service delivery models of AT devices.AT service delivery provision models such as PHAATE model may help clinicians and other medical professionals in Saudi Arabia to make informed decisions about the provision of AT device services.

Classification of wheelchair pressure relief maneuvers using changes in center of pressure and weight on the seat.

BACKGROUND: Pressure injuries from prolonged sitting are a significant problem for wheelchair users incurring high costs in healthcare expenditures and reducing quality-of-life. There is a need to improve pressure relief training and adherence in a variety of settings. OBJECTIVE: To identify effective common wheelchair pressure relief (PR) manoeuvres based on changes to users' seated centre of pressure (CoP) and seated weight. PARTICIPANTS: 20 individuals who use manual wheelchairs as their primary means of mobility. METHODS: Participants performed 5 types of PR including seated push-ups, leftward, rightward, forward, and backward leans-while sitting in a wheelchair equipped with a custom instrumented seat pan support. Data were analysed using both clustering and decision tree approaches to identify types of PR. RESULTS: Both clustering and decision tree approaches were able to identify and classify PR though neither could accurately distinguish between forward and backward PR. CONCLUSION: Changes in the centre of pressure and the total weight on the wheelchair's seat can be used to automatically characterise type, amplitude and duration of pressure relief manoeuvres. Building such a classification and quality assessment scheme into an algorithm could enable a virtual coaching system to track users' pressure relief behaviour and make suggestions to improve adherence with clinical recommendations.IMPLICATIONS FOR REHABILITATIONMultiple bending beam load cells can be used to measure wheelchair users' seated centre of pressure independent of type of cushion used.Both cluster analysis and decision tree algorithms can classify commonly practiced pressure reliefs by measuring changes to the centre of pressure and total weight on the wheelchair's seat.The combination of force sensing for centre of pressure determination and either algorithm could serve as the basis for an application to coach wheelchair users to do effective pressure reliefs.

Comparison of trunk mechanics and spatiotemporal outcomes in caregivers using a robotic assisted transfer device and a mobile floor lift.

OBJECTIVE: The purpose of this study was to compare trunk mechanics, distance covered, and average instantaneous velocity and acceleration recorded with caregivers performing transfer tasks using a research mannequin with both a prototype robotic assisted transfer device (RATD) and a mobile floor lift. DESIGN: Cross-Sectional. SETTING: Biomechanics Lab and Human Engineering Research Laboratories. PARTICIPANTS: Caregivers (N = 21). INTERVENTION: Robotic Assisted Transfer Device. OUTCOME MEASURES: Range of flexion-extension, lateral bend, and axial rotation; distance covered; average instantaneous velocity and acceleration. RESULTS: Caregivers performing transfers using the RATD as compared to when using the moble floor lift reported significantly smaller range of trunk flexion-extension, lateral bending, and axial rotation, and reported lower pelvic based distance covered and slower average instantaneous velocity and acceleration (P < 0.001). CONCLUSION: The design and usability of a RATD indicates design driven mobility advantages over clinical standard mobile floor lifts due to its ability to expand the workspace while further reducing risk factors for low back pain. While the concept is promising, further testing is required to address limitations and confirm the concept for clinical applications.

PURPOSE: The purpose of this study was to examine the effects of six weeks of routine use of a novel robotic transfer device, the AgileLife Patient Transfer System, on mobility-related health outcomes, task demand, and satisfaction relative to previous transfer methods. MATERIALS AND METHODS: Six end users and five caregivers used the system in their homes for six weeks. Participants completed several surveys examining perceived demands related to preparing and performing a transfer and mobility-related health outcomes pre and post intervention. Participants were also asked about their satisfaction with using the technology compared to previous transfer methods. RESULTS: Both end users and caregivers reported reduction in perceived physical demand (p = 0.007) and work (p ≤ 0.038) when preparing for and performing a transfer. End users indicated that the device intervention had a positive impact, indicating some improvements to health-related quality of life as well as improved competence, adaptability, and self-esteem post-intervention. All participants were highly likely to recommend the technology to others. CONCLUSION: The AgileLife Patient Transfer System is a promising new form of transfer technology that may improve the mobility and mobility-related health of individuals with disabilities and their caregivers in home settings.Implications for rehabilitationRobotic transfer assistance reduced physical demand and work among end users and caregivers.The robotic device had a positive impact on some quality of life outcomes after 6 weeks of use.Users were highly likely to recommend the robotic transfer device to others.

Anthropomorphic model rigid loading indenter with embedded sensor development for wheelchair cushion standard testing.

Develop an anthropomorphic model cushion rigid loading indenter with embedded sensors (AMCRLI-ES) to assess compression and shear forces at key locations such as trochanters and ischial tuberosities. The sensor design was optimized using finite element analysis. The AMCRLI-ES was designed with the same dimensions as specified in ISO 16840-2 tests. The AMCRLI-ES is divided into eight independent sections, and each section consists of one 3-axis load cell sensor to measure compression and shear forces normal to the compression direction. Six commercial cushions were tested using the AMCRLI-ES with standard ISO 16840-2 testing procedures. Statistical differences were found for energy dissipation between cushions. Statistical differences (p < 0.001) were found in all stiffness values. Test results showed that energy dissipation (ED) was correlated with hysteresis at 500 N with moderate to high Pearson product correlation r = -0.537, p = 0.022. The hysteresis at 250 N did not show a statistical correlation with ED. The AMCRLI-ES demonstrated the ability to measure compression and shear forces at key locations on the cushion including the thigh, trochanter, ischial tuberosity, and sacral area. It provides in-depth information about how the weight was distributed on the cushions.

Participatory action design and engineering of a manual wheelchair virtual coach including in-home and community usage.

BACKGROUND: Current clinical practice guidelines (CPG) recommend periodic pressure redistribution (PR) to alter sitting pressure and reduce the risk of developing pressure injuries (PI). Individuals who have strength and trunk stability are asked to perform PR such as wheelies, leaning laterally, and forward-leaning to minimize the duration of pressure acting on the same region of the body. OBJECTIVE: Our long-term objective is to build upon previous research and development to create a more effective device for improving PR training and adherence to CPG among manual wheelchair users (MWU). Through this study, we employed a participatory action design and engineering (PADE) approach in developing the hardware and user interface to increase the likelihood of eventually yielding a device effective for both MWU and clinicians. PARTICIPANTS: Focus Groups: Ten clinicians - 6 physical therapists, 3 occupational therapists, and one registered nurse, and 10 MWU with spinal cord injuries (SCI) who reported using their wheelchairs 40-80 h per week. Five-Day Assessment: Five male MWU with SCI who had been wheelchair users for 18.5 ± 16.2 years. Four-Week Investigation: The 7 participants with SCI were 5 males and 2 females, who had been wheelchair users for 24.7 ± 17.0 years. METHODS: A PADE approach was used to improve upon a manual wheelchair virtual coaching system for people with SCI. The system comprises a seat support instrumented with force sensors, software algorithms to detect PR, and a smart phone app for user interface. The methods included three stages: multiple focus groups, a five-day evaluation phase with participants using their own wheelchairs in their homes and communities, and a 4-week assessment with improvements made based on the 5-day results by users with their own wheelchairs in their homes and communities. RESULTS: The focus groups yielded guidance for ergonomics, user interface, charging frequency, and key dimensions and mass. The 5-day study identified mechanical, electrical, and connectivity challenges, which were resolved before the 4-week study. The 4-week trial suggested that participants performed PR less frequently than clinically recommended and provided an indication of the types of maneuvers that they performed. CONCLUSION: A prototype manual wheelchair virtual coaching system was developed using a PADE process. The system was able to detect and record PR in home and community environments. Following improvements identified in this study, a future version will be tested with additional users to determine whether it can improve adherence to PR guidance.

Conceptual mapping proposed to comprehend the effect of wheelchair mobility on social participation and quality of life: a systematic review.

PURPOSE: To identify and synthesise the available evidence on the effect of mobility on social participation and quality of life (QoL) of wheelchairs (WC) on adults who use WC as their primary means of mobility. MATERIALS AND METHODS: Systematic review undertaken in accordance with the Centre for Reviews and Dissemination Guidelines and registered in the PROSPERO International Prospective Register of Systematic reviews. Nine electronic databases (MEDLINE via PubMed, EMBASE, Cochrane Library, LILACS, CINAHL, PEDro, SCOPUS, Web of Science, and BVS ECOS) were searched with the following PICO eligibility criteria: (P) Population was individuals with mobility limitations that live in their community, aged 18 or older; (I) Intervention was mobility devices, such as manual and powered wheelchairs; (C) Comparators, not applied; (O) Outcome was factors that can be influenced by wheelchair use, such as: social participation, health-related quality of life and QOL. Critical appraisal of methodological quality of studies were undertaken. RESULTS: A total of 18 studies were included. The proportion of studies evaluating the effects of mobility on participation was higher than to mobility on QoL. WC quality, device benefit (ease of repairs and maintenance), confidence using a WC and WC skills were key factors determining participation. The provision of WC according to the eight steps service proposed by the Word Health Organisation contributed to higher levels of physical health, WC satisfaction, hours using the WC and QoL enhancement. CONCLUSION: Attention should be given to enhance WC service provision (with continuous service support) as well as professional continuing education.IMPLICATIONS FOR REHABILITATIONWheelchair technology is a key element in rehabilitation. Significant effort should be made to provide and maintain the wheelchair as a facilitator to participation. A great attention should be done to enhance wheelchair services as well as professional continuous education.Wheelchair skills are associated with participation and may be targeted in clinical intervention.

Clinical and Ergonomic Comparison Between a Robotic Assisted Transfer Device and a Mobile Floor Lift During Caregiver-Assisted Wheelchair Transfers.

BACKGROUND: The robotic assisted transfer device was developed as an updated lift technology to reduce adjustments in posture while increasing capabilities offered by transfer devices. The purpose of this study was to compare the trunk biomechanics of a robotic assisted transfer device and a mechanical floor lift in the transfer of a care recipient by a caregiver during essential transfer tasks. METHODS: Investigators enrolled 28 caregiver/care recipient dyads to complete 36 transferring tasks. Surface electromyography for the back muscles and motion data for trunk range of motion were collected for selected surfaces, phase, and direction tasks using a robotic assisted transfer device and a mechanical floor lift. RESULTS: Robotic assisted transfer device transfers required significantly smaller range of trunk flexion (P < 0.001), lateral bend (P < 0.001), and axial rotation (P = 0.01), in addition to smaller distance covered (P < 0.001), average instantaneous velocity (P = 0.01), and acceleration (P < 0.001) compared with a mobile floor lift. The robotic assisted transfer device transfers required significantly smaller peak erector spinae (left: P = 0.001; right: P < 0.001) and latissimus dorsi (right: P < 0.001) and integrated erector spinae left (P = 0.001) and latissimus dorsi right (P = 0.01) electromyography signals compared with the floor lift. CONCLUSIONS: The robotic assisted transfer device provides additional benefits to mobile floor lifts which, coupled with statistically lower flexion, extension, and rotation, may make them an appealing alternative intervention.

Analysis of Whole-Body Vibration Using Electric Powered Wheelchairs on Surface Transitions.

Wheelchair users are exposed to whole-body vibration (WBV) when driving on sidewalks and in urban environments; however, there is limited literature on WBV exposure to power wheelchair users when driving during daily activities. Further, surface transitions (i.e., curb-ramps) provide wheelchair accessibility from street intersections to sidewalks; but these require a threshold for water drainage. This threshold may induce high WBV (i.e., root-mean-square and vibration-daily-value accelerations) when accessibility guidelines are not met. This study analyzed the WBV effects on power wheelchairs with passive suspension when driving over surfaces with different thresholds. Additionally, this study introduced a novel power wheelchair with active suspension to reduce WBV levels on surface transitions. Three trials were performed with a commercial power wheelchair with passive suspension, a novel power wheelchair with active suspension, and the novel power wheelchair without active suspension driving on surfaces with five different thresholds. Results show no WBV difference among EPWs across all surfaces. However, the vibration-dose-value increased with higher surface thresholds when using the passive suspension while the active suspension remained constant. Overall, the power wheelchair with active suspension offered similar WBV effects as the passive suspension. While significant vibration-dose-value differences were observed between surface thresholds, all EPWs maintained WBV values below the ISO 2631-1 health caution zone.
